EDMON LESLIE, OF MARSHALLTOWN, IOWA.

SMOKE-CONSUMER.

To all whom it may concern:

Be it known that I, EDMON LESLIE, a citizen of the United States,residing at Marshalltown, in the county of Marshall and State of Iowa,have invented a new and useful Smoke-Consumer, of which the following isaspecification.

The object of my invention is to provide a smoke consumer of simple,durable, and inexpensive construction, designed to be placed in a firebox.

A further object of my invention is to provide a smoke consumer soconstructed and arranged that it may be detaohably mounted in a fire boxand having parts which may be readily and easily removed or taken apart.

A further object is to provide a smoke consumer arranged in a fire boxso that the products of combustion pass through a series of openings soarranged as to somewhat retard such passage and provided with partswhich are heated so that the smoke and heavier products of combustionpassing through the consumer are burned before being discharged throughthe smoke stack.

A further object is to provide a smoke consumer provided with meanswhereby fresh air is admitted to the consumer and mingled with theproducts of combustion passing therethrough.

My invention consists in certain details, in the construction,combination, and ar rangement of the various parts of my device, wherebythe objects contemplated are attained, as hereinafter more fully setforth, pointed out in my claims, and illustrated in the accompanyingdrawings, in which Figure 1 shows a vertical, longitudinal, sectionalview through aboiler and a fire box equipped with a smoke consumerembodying my invention. Fig. 2 shows an end elevation partly in section,of my improved smoke consumer on a larger scale than in Fig. 1. Fig. 3shows a sectional view on the line 33 of Fig. 2. Fig. 4 shows a central,vertical, sectional view through one of the cylinders of my improvedsmoke consumer. -Fig. 5 shows a i stalled 1n position to extend from apoint perspective view of the detachable slide which is received in theportion of the smoke consumer between two sections. Fig. 6 shows asectional view of one of the fiues over the fire box, showing the meansfor admitting fresh air thereto.

In the accompanying drawings, I have Specification of Letters Patent.

shown my smoke consumer installed in a steam boiler in which the boileris indicated by the reference numeral 10. On the boiler is a steam dome11. Below the rear end of the boiler is a water jacketed fire box 12 inwhich is a door opening 13. Above the fire box is what I will call amain crown sheet 14 and below that is a second crown sheet 15. Extendingforwardly through the boiler from the fire box 12, are a plurality offiues 16. Two of the lines areindioated by the reference numeral 17 andextend rearwardly from the fire box between the crown sheets 14 and 15and at their rear ends communicate with the other rear end of the firebox. Communicating with the fiues 17 near their rear ends are smalltubes 18 which extend through the walls of the boiler and through whichair may be drawn into the lines 17. Mounted in the fire box is myimproved smoke consumer which I have indicated generally by thereference numeral A in Fig. 1.

The smoke consumer A is constructed as follows: I provide detachablesections of which there maybe as many as necessary. Each section ispreferably composed oftwo cylinders 19 and 20 which are spaced apartfrom each other and are connected by flat upper and lower walls 21and22. Extending laterally from the cylinder 19, on the opposite sidefrom and in line with the'wall 21, is a wall 23 having at its end aflange 24 extending upwardly and away from the cylinder 19 when thesmoke consumer is installed. On the cylinder 20, on the sideopothersuitable means, as shown in Fig. 2.

As many of thesmoke consumer sections may be used as desired andplacedtogether. p My smoke consumer 1s designed to be innear the upper rearend of the fire box to a point near the forwardend thereof spaced abovethe grate. On the outer ends of'the sections adjacent to the top and tothe forward end of the fire box, I provide, instead of the'flang s 24and 26 extensions 27 and 28 which are substantially rectangular in crosssection and are designed to rest against the top and forward wallsrespectively of the fire box. The lower half of the ends of eachcylinder 19 and 20 is open as shown in Fig. 2 and I provide a detachablehalf cylinder designed to be received in the lower half of each cylinder19 and 20, each half cylinder being provided with a perforated flat top30 and with a wire wall 31.

Near each end of the top 30 of each half cylinder, is a downwardlyextending transverse plate 32. At each end the half cylinders areprovided with semi-circular ends 33 designed to fill the openings in thecylinders 19 and 20. In the upper and lower halves of the cylinders 19and 20 are openings 34 and 35 and in the top 30 of the half cylinders,are openings 36. The openings 34, 36 and 35 are graded in size, theopenings 34 being larger than the openings 36, and the openings 36 beinglarger than the openings 35, as clearly shown in Fig. 4. The walls 21and 22 are connected at one end by a wall 37. In the walls 22 and 21 areopenings 38 and 39, the openings 38 being larger than the openings 39. Iprovide a tray 40 of wire or other meshed material, designed to bereceived above the wall 22, between each adjacent pair of cylinders.Upon one end of the tray 40 is an upwardly extending plate 41 de signedto close the opening between the walls 21 and 22 opposite the wall 37when the tray is installed in position. The purpose of the tray 40 andof the half cylinder above described, is largely to prevent thedischarge of sparks into the flues 16.

The cylinders above described are mounted in the fire box in thefollowing manner: At suitable intervals, openings are provided in thedouble walls of the sides of the tire box and in the openings aremounted water tight cylinders 42 which are in communication with theinterior of the fire box and with the air outside. In the ends 33 of thehalf cylinders are openings 43. Mounted in the cylinders 42, I providecylinders 44, the inner ends of which are designed to be received in theopenings 43, as shown in Fig. 4. By means of the cylinders 44, the halfcylinders and the cylinders 19 and 20, are supported within the firebox. Near the outer ends of the cylinders 44, are circumferential,annular flanges 45, designed to limit the inward movement of thecylinders 44. On the walls of the fire box are spring clips 46 designedto engage the flanges 45 and to hold the cylinders 44 in position.

In the practical installation of my improved smoke consumer, the sectionthereof on which the portion 28 is formed is placed in the fire box withthe end of the portion 28 placed against the top of the fire box justrearwardly from the openings into the flues 17. Before being placed inthe fire box,

the half cylinders are placed within the cylinders and the trays 40 areplaced in position between the cylinders. The cylinders 45 are placed inposition with their inner ends received in the openings 43 and the uppersection of the smoke consumer is thereby held in position. The nextadjacent section is then placed in position with the flange 26 restingadjacent to the cylinder 19, and the flange 24 resting adjacent to thecylinder 20. The third section is then placed in position with theportion 20 resting against the forward wall of the fire box.

As shown in Fig. 1, the smoke consumer consists of three sections. It isunderstood that as many sections as are necessary may be used. It willalso be understood that many variations may be made in details of theconstruction of my smoke consumer without departing from its essentialpurpose.

In the practical operation of my improved smoke consumer, the fire boxis filled with fuel and air is admitted thereto in any suitable way. Theproducts of combustion passing upwardly in the fire box, pass throughthe smoke consumer. A small part of the products of combustion pass intothe flues 17, wherein they are mingled with air admitted through thetubes 18 and are largely consumed before being discharged from saidflues. The larger part of the product of combustion passes through thesmoke consumer. The passage of cinders or chunks is prevented by thescreen 40 and the screen composing the lower portion of the halfcylinders. Smoke and the like pass through the openings 34 into the halfcylinder where they are mingled with air admitted though the tubes 45.The air is first directed downwardly by the plates 32 and is thoroughlymingled with the products of combustion. The air and products ofcombustion pass upwardly through the openings 36, being somewhatretarded by the fact that the openings 36 are smaller than the openings34. The products of combustion mingled with air then pass through theopenings 35 into the flues 16. It will be understood that the productsof combustion are somewhat retarded before passing through the openings35. The upper portions of the cylinders are thoroughly heated and theproducts of combustion are almost entirely consumed before passing intothe flues 16.

The advantages of my improved smoke consumer are seen from the foregoingdescription.

The passage of burning sparks or cinders from the engine is prevented bythe screens hereinbefore described. Products of combustion arethoroughly consumed in passing through the smoke consumer, as set forthin the foregoing paragraph describing the operation thereof. consumer issuch that the parts thereof may be readily taken out for cleaning,repairing or replacing them. The parts may be taken out in sections sothat the operation is not difficult.
